[IMPROVEMENT m CRADLES.

Specification forming part of Letters Patent No. 138,320, dated April 29, 1873; applicat'on filed March 8, 1873. r

I?) all whom it may concern:

lower ends of the posts or legs B of which are pivoted detachably the cranks 0, which are also pivoted to the ends of the cross blocks D, so that the cradle A B may be oscillated longitudinally, if desired. The middle parts of the cross-blocks Drest upon and are secured to the tops of the columns E. The columns E are formed by alternate rubber and wooden blocks, placed one upon another, and connected by a jointed or flexible rod, which also passes through the cross blocks D and footblocks E.

The upper and lower sides of the wooden blocks, or of all the blocks, may be rounded ofi, as shown in Fig. 1, so that the columns E may be flexible.

The flexible or jointed connecting-rods of the columns E should be provided, at one or both ends, with a washer and nut, so that the wear may be taken up, and the tension of the springs adjusted as required.

The lower ends of the columns E rest upon the foot-blocks F, to which they are secured by the flexible or jointed connecting-rods.

The ends of the foot or base blocks F are inclined; and the said blocks F are made of such a length that their inclined ends may serve as stops for the lower ends of the posts B of the cradle A B to strike against when the cradle is rocked to prevent it from rocking too far.

The foot -blocks F are connected by a bar, G, to prevent them from getting out of their proper relative positions.

By this construction the cradle may be oscillated longitudinally upon the cranks G with a gentle movement; or more vigorously by adding the sway of the flexible columns E to the swing of the said cranks (l or the cradle may lie rocked laterally by the sway ofthe columns Having thus described my invention, I claim as new and desire to secure by Letters Patent-- The flexible supporting-columns E, in combination with the cranks C and cradle A B, substantially as herein described.
